Re: [web2py] Re: Sticky sessions in a distributed environment
Right. Then why does the whole ticketting system depend on admin ? It is even said in the Deployment Recipe chapter of the doc http://www.web2py.com/books/default/chapter/29/13/deployment-recipes#Collecting-tickets : You can later view the errors *using the admin app*, clicking on the switch to: db button at the top, with the same exact functionality as if they were stored on the file system. Same goes for appadmin.py and its permission-based manage feature which is described as a role-based database access. Why would you define roles in a local environment ? Obviously this is meant to go on production in a secure back-office... Admin is designed as more than a testing tool for a local or development environment, yet it is not meant to be deployed on production. I now get why many blogs and forums discussing web2py vs other framework always end up mentionning that developping on web2py starts as a very thrilling experience but often leaves a bitter taste.

Re: [web2py] Re: multiple select plugin and list reference
I think I was a little quick to write it works. The multiple select shows
but the entries won't move to the second box. So no function of the widget
at all.
How do I open up the console to check for javascript errors?

[web2py] Re: Sticky sessions in a distributed environment
I don't think commenting about my age is any more mature than what you claim I would be... Anyway, contributing is amongst my current preoccupations - as I mentionned in another post. The thing is : my disappointment here lies in the architecture, not the features. There is little contribution to be done when regarding an architectural issue (except a big refactoring of course, which you can't expect a regular contributor to do on his own). Web2py provides a lot of features, and they are supposed to be adapable and easy to include with your own application. In many ways, I find this is not true. My personal experience is that I put a lot of time and effort to try and work as close to web2py as I could, and now when I try to make my app evolve I end up either cutting from web2py (i.e. rebuilding the whole feature with custom code instead of using web2py's) or deleting the feature altogether. Perhaps web2py is too feature-intensive to be truly adaptable, perhaps it is too education-oriented to work quite well in other domains (mine would be e-commerce)... I think it is fair to share personal experiences regarding the framework (good or bad), as long as they are relevant.

[web2py] Re: Web2py's included connection pooling VS external pooling software
I go back to this thread because today I ran with the same problem: postgresql reaching max_connection limits and, therefor, some of my websites throwing intermitent HTTP 500 errors (because web2py couldn't connect to the database). To remind, we are talking of a VPS with multiple instances of web2py running, all of them serving the same web2py app, each one connecting to a different postgresql database (however the database structure is the same accross all the databases). Each web2py instance is served by a lighttpd virtual host through fastcgi. Each virtual host (that is, each web2py instance) receives a different volume of traffic (that is obvious, they are different websites with different public). The original problem (the one that caused I post this question in the first place) was that the postgresql database server was reaching the max_connections limit and, in consecuence, some of the websites were throwing intermitent HTTP 500 errors (web2py couldn't connect to database). Then, the user oriented me with pool_size parameter of DAL constructor. Thanks again! I've been reading the web2py documentation about pooling [1] and I notice that it says that When the next http request arrives, web2py tries to recycle a connection from the pool and use that for the new transaction. If there are no available connections in the pool, a new connection is established. So, if I didn't get it wrong, I deduce that with web2py's pooling mechanism I can't overcome the max_connections postgresql limit. That is because, no matter the size of the pool, if the pool is full and the website is receiving a lot of requests, new connetions will be created, and eventually the database server will reach the max_conectios limit. So, I read about pgBouncer [2], with special attention to the configuration parameter max_client_conn [3]. Also I've found this two posts [4] [5] explaining that this parameter can be set in **any** number, independently of the max_connections postgresql configuration. Therefor, ¿is it ok to say that web2py's pooling mechanism **won't** let you overcome postgresql max_connections limit, but in the other hand, you **will** be able to overcome that limit using pgbouncer? Thanks in advance.

[web2py] Re: Sticky sessions in a distributed environment
Any project will eventually outgrow any framework it uses, when that happens you can either contribute to the framework if it makes sense or just do it yourself for that application. The advantage is that with web2py you can use the included tools while you don't reach that moment while with a more bare-bones framework you don't even get that option. I think it is fair to share personal experiences regarding the framework (good or bad), as long as they are relevant.

[web2py] Domain model and web2py DAL
Hi. I'd like to use the domain model pattern and keep database access code outside models. It seems to me that using a simple database abstraction layer such as web2py DAL better fits to transaction script (no domain models or anemic domain model - models reflect tables) or active records (models have data, logic and data access) design patterns. It seems to me that using a full domain model fits better with the data mapper pattern and probably I should use an ORM. You agree?

I have a Java client talking to my Web2Py service.
My imports include javax.xml.soap.xml, and i instantiate using

I also have a Python client that talks to the same service using suds

work. Mariano seems to have a very good library for us to leverage.

[web2py] Including a label inside a form field
I have a series of form elements as follows
form = SQLFORM.factory (
Field ('client',
requires=IS_IN_SET (['Client','Rhubarb','Custard','Bogies']),
default='Client'),
Field ('portfolio',
requires=IS_IN_SET (['US Equity','Multi Asset
ETF','Portfolio']),
default='Portfolio'),
Field ('benchmark',
requires=IS_IN_SET (['SP 500','Custom Policy','Benchmark']),
default='Benchmark'),
Field ('methodology',
requires=IS_IN_SET (['Brinson-Fachler',
'Regression','Method']),
default='Method'),
Field('level1',
requires=IS_IN_SET(['Sector','Industry','Asset Class', 'Level
1']),
default='Level 1'),
Field('level2',
requires=IS_IN_SET(['Sector','Industry','Asset Class', 'Level
2']),
default='Level 2'),
Field ('start_date', 'date', default=Start Date),
Field ('end_date', 'date', default=End Date)
).process ()
I have a slightly fumble fingered approach to set a label inside each form
field instead of as a label above or alongside as shown in the code, by
setting the label as a default. The page this input form will be used for
is a busy one and space is at a premium.
Is there a more elegant way to put form labels into the form field that
won't fail on the dates inputs?
As a side question, the approach above displays the default inside the
widget for Method, Level 1 and Level 2, but not for client, portfolio and
benchmark. Is there something wrong with my code that would cause that?

[web2py] Running scheduler on OS X - problem with urllib.getproxies() and multiprocessing
Hi, I'm just wondering if anyone has experienced the same problem or not. Basically, I get a segmentation fault (scheduler process killed by signal 11) if I try to start more than one scheduler under OS X. The problem can be reproduced with the built-in welcome app by adding a models/scheduler.py: from gluon.scheduler import Scheduler SCHEDULER = Scheduler(db) and then start the scheduler like this: ./web2py -K welcome,welcome I'm running web2py R-2.9.11 with python 2.7.8 (also same result with apple's python 2.7.6) on OS X 10.10.1(also got the same result on Maverick). I've managed to track down the problem to the getproxies() call in urllib which leads me to this bug: http://bugs.python.org/issue9405 By following the suggestion in the bug report, I was able to work around this problem by this patch: diff --git a/gluon/widget.py b/gluon/widget.py index cf885ae..62a38ee 100644 --- a/gluon/widget.py +++ b/gluon/widget.py @@ -1051,6 +1051,11 @@ def start_schedulers(options): print 'starting single-scheduler for %s...' % app_ run(app_, True, True, None, False, code) return + +# Work around OS X problem: http://bugs.python.org/issue9405 +import urllib +urllib.getproxies() + for app in apps: app_, code = get_code_for_scheduler(app, options) if not app_: Just wanted to throw this out in case anyone meets the problem.

A drawback of that change will be that with the post, a user is not able to bookmark the search result. In addition to not allowing bookmarking, POST will cause problems if the user does a refresh or hits the back button (i.e., the browser will ask if you want to re-submit the form data).

[web2py] set form value from a session object
Hello (and Happy Thanksgiving)
I've walked through the tutorials about creating a simple model (db table)
then using the controller and view to automatically generate forms with
validation. They are GREAT!
My problem is when I tried to modify the form.
For example, I created a simple model that stores timecard related data.
db.define_table(
'time_record',
Field('firstName',requires=IS_NOT_EMPTY() ),
Field('lastName',requires=IS_NOT_EMPTY() ),
Field('userId',requires=IS_NOT_EMPTY() ),
Field('clientCode', requires = IS_INT_IN_RANGE(10,20) ),
Field('dateOfWork', type='date', requires = IS_DATE() ),
Field('hours', requires = IS_FLOAT_IN_RANGE(0.1,16.0) )
)
Next, I build the controller:
def create_time_record():
return dict(form=crud.update(db.time_record,request.args(0)))
Next, I have the view:
{{extend 'layout.html'}}
{{ = form }}
Instead of the user entering the data in the form, I want to set one of the
form fields to be invisible (or disabled) and automatically get its values
from the session object from the log in, for
example, session.auth.user.first_name. I can easily display auth data (id,
first_name, last_name) but I cannot set this data into the form.
{{ = form }} is so simple and powerful, yet how to I access a specific form
element, set its value, and not affect the overall form validation process.
Thank You All!
Terry

[web2py] Re: (de-)select values for the multiselect_widget from ScubismLabs.
This topic can be closed. Instead of using the sqlform.factory()-statement, you can just set db.table.field.widget = multiselect_widget. To activate the widget for this field.

However I do have one small issue with the “multiselect_widget”, which could be due to the fact that I don’t know how to implement the plugin properly. The problem I’m currently facing is the fact that I don’t know how to preselect values. For instance, I’m trying to create a page where a user’s membership can be rectified. The administrator first have to select a username (based on a dropdown from), afterwards the 2 boxes(“member of” and “Not member of”) should display the memberships of that specific user. And this is the point where I’m stuck. All the groups seem to end up in the same box, and I can’t figure out how to make the selection of “members” and “nomembers”. And I just wanted to know that I’m not doing something wrong, and I’m not forgetting something.

Re: [web2py] Re: Sticky sessions in a distributed environment
ticketing doesn't depend on admin, and you - again usually - don't want to see errors on the production server. Just copy errors over and see them on your development instance (or let the script tickets2email.py send the errors over to you). And...in a production server appadmin.py isn't needed. BUT you're right. Given that it kinda does work on GAE, it should kinda work on other diskless PaaS as well.

[web2py] Re: Web2py's included connection pooling VS external pooling software
On Friday, November 28, 2014 3:31:02 PM UTC+1, Lisandro wrote: I go back to this thread because today I ran with the same problem: postgresql reaching max_connection limits and, therefor, some of my websites throwing intermitent HTTP 500 errors (because web2py couldn't connect to the database). To remind, we are talking of a VPS with multiple instances of web2py running, all of them serving the same web2py app, each one connecting to a different postgresql database (however the database structure is the same accross all the databases). Each web2py instance is served by a lighttpd virtual host through fastcgi. Each virtual host (that is, each web2py instance) receives a different volume of traffic (that is obvious, they are different websites with different public). The original problem (the one that caused I post this question in the first place) was that the postgresql database server was reaching the max_connections limit and, in consecuence, some of the websites were throwing intermitent HTTP 500 errors (web2py couldn't connect to database). Then, the user oriented me with pool_size parameter of DAL constructor. Thanks again! I've been reading the web2py documentation about pooling [1] and I notice that it says that When the next http request arrives, web2py tries to recycle a connection from the pool and use that for the new transaction. If there are no available connections in the pool, a new connection is established. So, if I didn't get it wrong, I deduce that with web2py's pooling mechanism I can't overcome the max_connections postgresql limit. That is because, no matter the size of the pool, if the pool is full and the website is receiving a lot of requests, new connetions will be created, and eventually the database server will reach the max_conectios limit. no, you got it wrong again. pool_size=5 will create AT MOST 5 connections . if a 6th is needed, users will wait for a connection to be freed. if your postgresql accept at most 50 connections, do the math. Every db = DAL(, pool_size=5) lying around will create AT MOST 5 connections, and that means you can host 10 apps. If you need 50 apps, set pool_size=1 and let users wait, or set max_connections in postgres to a higher value. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: add task and wait the result
Related, but not exactly the same question: I'm submitting an immediate task in a regular (no sleep or anything -- though no special commit either); I can see it's queued for seconds and sometimes minutes before getting assigned and running. There are no other tasks waiting or running, there are one or two schedulers running (one starts with app server, one independently - but I tried only one with same results). Before I dig deep into debugging the scehduler - is there something simple I might be missing? Other things: main app db, auth db and sched db are all different, and all are SQLite files. Running on Linux. Tasks are given a uuid by me (easiest way to track if something was done in a previous run or not - uuid reflects the exact operation needed). Thanks in advance.

[web2py] Re: set form value from a session object
To make a field un-writable, set its writable attribute to False. To
completely remove it from the form altogether, you can also set its
readable attribute to False. If you would like the field to get a default
value based on data in the session, you can set the default and/or
update attributes of the field based on the session values.

[web2py] Pagination within a SQLFORM.factory
I want to let the user do a query and paginate through the resulting table. grid/smartgrid would be great, except that I need to supply the query through a form and not leave it open -- the query has minimum and maximum values for most fields, multiple selects for others (I build the search query form itself with SQLFORM.factory, though it can be done any other way).

Re: [web2py] Re: Web2py's included connection pooling VS external pooling software
Mmm... I see. That was my understanding in the first place. At that time I did the maths, I had 10 apps, each one using a pool_size of 3. In postgresql.conf max_connections was set to 80. However this morning, with those numbers, almost every of my websites was throwing intermitent HTTP 500 errors, and the error tickets were all the same: FATAL: remaining connection slots are reserved for non-replication superuser connections. Right now, I have almost 13 websites, all of them with pool_size in 3, and max_connections in 80. However, if I check the table pg_stat_activity I can see 65 connections, and I can see there is 5 connections per app. I've tried even setting pool_size to 1 for one of the apps, restarted database server and webserver, but again I check pg_stat_activity and I see 5 connections for that app. ¿Am I missing something too ovbious? 2014-11-28 14:25 GMT-03:00 Niphlod niph...@gmail.com: On Friday, November 28, 2014 3:31:02 PM UTC+1, Lisandro wrote: I go back to this thread because today I ran with the same problem: postgresql reaching max_connection limits and, therefor, some of my websites throwing intermitent HTTP 500 errors (because web2py couldn't connect to the database). To remind, we are talking of a VPS with multiple instances of web2py running, all of them serving the same web2py app, each one connecting to a different postgresql database (however the database structure is the same accross all the databases). Each web2py instance is served by a lighttpd virtual host through fastcgi. Each virtual host (that is, each web2py instance) receives a different volume of traffic (that is obvious, they are different websites with different public). The original problem (the one that caused I post this question in the first place) was that the postgresql database server was reaching the max_connections limit and, in consecuence, some of the websites were throwing intermitent HTTP 500 errors (web2py couldn't connect to database). Then, the user oriented me with pool_size parameter of DAL constructor. Thanks again! I've been reading the web2py documentation about pooling [1] and I notice that it says that When the next http request arrives, web2py tries to recycle a connection from the pool and use that for the new transaction. If there are no available connections in the pool, a new connection is established. So, if I didn't get it wrong, I deduce that with web2py's pooling mechanism I can't overcome the max_connections postgresql limit. That is because, no matter the size of the pool, if the pool is full and the website is receiving a lot of requests, new connetions will be created, and eventually the database server will reach the max_conectios limit. no, you got it wrong again. pool_size=5 will create AT MOST 5 connections . if a 6th is needed, users will wait for a connection to be freed. if your postgresql accept at most 50 connections, do the math. Every db = DAL(, pool_size=5) lying around will create AT MOST 5 connections, and that means you can host 10 apps. If you need 50 apps, set pool_size=1 and let users wait, or set max_connections in postgres to a higher value. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to a topic in the Google Groups web2py-users group.

[web2py] Re: Pagination within a SQLFORM.factory
The grid allows you to implement a custom search widget (via the search_widget argument) as well as a custom server-side search function (via the searchable argument) to build a query based on the keywords returned by the widget. This isn't well documented, so you'll have to look at the source code to figure out what the widget and searchable function should look like.

Re: [web2py] Re: Sticky sessions in a distributed environment
Louis, I think you're getting a little pushback because you make a rather extreme criticism in the face of a fairly small issue that (a) you can easily work around right now and (b) would not be difficult to fix in the framework. Furthermore, the issue at hand affects features of web2py (i.e., admin and appadmin) that most other frameworks don't even have. Note, aside from adding a few lines in the admin app to have its sessions stored in the db, another option might be to edit the handler file used to start web2py. In that file, you should be able to do something like this: from gluon.settings import global_settings global_settings.db_sessions = True Your handler file shouldn't change on web2py upgrade, so this setting will remain in effect. If all you really need is appadmin, then you could also directly edit the appadmin.py controller so it uses the Auth of its own app rather than the admin app (this won't change when you upgrade web2py because the appadmin.py file is part of the app code and is not automatically overwritten on upgrade). In fact, this is already how the appadmin manage feature works, so if that feature is adequate for you, you don't need to make any changes at all. As for error tickets, if you want them to go directly into the db instead of initially being written to the filesystem, I think you can add the following in a model: request.tickets_db = db To then view the tickets via admin, you need a ticket_storage.txt file in the app's /private folder that includes the URI if the database. I suppose this poses a problem on Heroku, so we may need to come up with an alternative means of getting the URI. More generally, perhaps we could add a feature that would allow a flag to be set indicating that the runtime environment lacks a persistent filesystem, in which case, sessions and error tickets would automatically go in the database. The framework obviously already includes the needed functionality, as this is what is done on GAE -- we just need to generalize the setting so it can be used on any platform. The thing is : my disappointment here lies in the architecture, not the features. There is little contribution to be done when regarding an architectural issue (except a big refactoring of course, which you can't expect a regular contributor to do on his own). I don't think this is an architectural issue or requires a big refactoring. We already have the functionality in place to work on GAE -- it just needs to be tweaked to apply more generally. I think it is fair to share personal experiences regarding the framework (good or bad), as long as they are relevant. Of course, but consider the tone. Every improvement to web2py is contributed by a volunteer. Same goes for appadmin.py and its permission-based manage feature which is described as a role-based database access. Why would you define roles in a local environment ? Obviously this is meant to go on production in a secure back-office... As noted above, the manage feature of appadmin does not in fact delegate authorization to the admin app. It instead relies directly on the app's own Auth system (which is how it is able to use role-based authorization). In any case, I agree that to the degree that it is feasible, it should be possible to run admin and appadmin in production. They are probably not the ideal tools in serious production environments, but they have their place as a convenience in some settings. We should be realistic, though -- if you don't have a persistent filesystem, the admin app will have its limitations.

Re: [web2py] Re: Domain model and web2py DAL
You could see DAL as a scoped ORM i.e. for specific kind of objects, these object are Table(s) containing Field(s) and the way to manipulate those objects mimics as much as possible the relational model. By no mean DAL is thin. As a matter of fact it allows extremely sophisticated thing like accessing an IMAP server with relational semantics. The connection code is one liner and you can put it anywhere you please, there is hardly the need to write any SQL by hand. Indeed I often use the DAL as a reference to generate SQL that I need to use in places where I can't use the DAL itself... 2014-11-28 20:51 GMT+01:00 Anthony abasta...@gmail.com: I suppose it depends on your requirements, though note that the web2py DAL isn't *that *simple -- you might find you can get pretty far with things like virtual fields http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#Virtual-fields, table inheritance http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#Table-inheritance, and table methods https://groups.google.com/forum/#!msg/web2py/ceqq4JwkWi4/csn0kZfyPuwJ.

setting the label as a default. The page this input form will be used for

Is there a more elegant way to put form labels into the form field that
won't fail on the dates inputs?
As a side question, the approach above displays the default inside the

[web2py] web2py with bootstrap-slider bootstrap-typeahead
Hy everyone.
I'm working with web2py since one year. In most cases it's a fine and easy
way to develop a nice working web app.
Now i want to create a new web application in web 2.0 design.
For this i want to use more bootstrap components
i need to use the bootstrap slider
http://seiyria.github.io/bootstrap-slider/
and the autocomplete extension
https://twitter.github.io/typeahead.js/examples/
i've downloaded the java scripts and css files and placed them to the js
and css directory.
After this, i added
link href={{=URL('static', 'css/bootstrap-slider.css')}} rel=stylesheet
type=text/css /
script src={{=URL('static','js/bootstrap-slider.js')}}/script
in my view html file.
i also added a sample in my view file..
input id=ex1 data-slider-id='ex1Slider' type=text data-slider-min=0
data-slider-max=20 data-slider-step=1 data-slider-value=14/
script
$('#ex1').slider({
formatter: function(value) {
return 'Current value: ' + value;
}
});
/script
style
#ex1Slider .slider-selection {
background: #BABABA;
}
/style
But it does not work.
Just a empty input filed is displayed..
I added a alter in the slider.js file. This works - alter call is
displayed.
Can anybody help me??
